hey guys i am having some trouble with my 04, when i start it up it takes a really long time to warm up and it will quit if i don't run it with the choke, it also backfires a lot on decel at high speeds. and just recently it started getting harder to start cold. i just adjusted the valves and they are in spec so do you guys think it is running lean or what?

check your plug and see what color it is.. You might want to mess with the fuel screw a little. If it gets more then 3 1/2 -4 turns out then you will have to bump up the pilot jet


it could also clogged jet(s)

you might want to check the float and vale seat could be clogg and the float height might be too low and the bike is starving for some fuel...how is the bike once its one? and warm?

      2015 Kawasaki KX250f - 20 hours
      As close to new as I'd imagine you'd get! I bought the bike brand new, I'm older and have taken extremely good care of this bike. Very little use and is COMPLETELY stock - everything is original. 
      Comes with the title, original book and map couplers for the fuel injection.
      $4700 - cash

      Just thought maybe everyone could post up there youtube channels an we could all help eachother out by subscribing to one another.
      Heres mine ill sub back asap.
      This has been fun in other sections of TT, so I'll start the thread here and see if we can keep it going.
      Let us know what kind of mods, fixes, changes, etc.., you performed today, or just general fun you had with, your KX250F.
      I'll start with.. I installed a correct for my weight Race Tech shock spring, along with a Pivot Works shock spring thrust bearing. Also cleaned out all the nasty yellow plastic/wax crap that passes for grease in the lower shock bearing, and re-lubed it with Bel Ray waterproof.

      Time for a top end on my bike, just wondering if there are any alternative Valve springs i can use. I have PC cams and $400 for just the springs and retainers is alil costly at the moment.
